Abstract (en)
Provided is a trigger-type ejector (1, 100) including: a pressure storage chamber (58) defined and formed in a nozzle head (50) and communicating with a flow path (P2) through a communication hole (52f); a pressure storage plunger (53) including a large-diameter pressure receiving portion (53c) and a small-diameter pressure receiving portion (53e) facing an opposite side to the large-diameter pressure receiving portion (53c) and being movable between a close position where an ejection hole (51c) is closed and an open position where the ejection hole (51c) is opened; and a biasing member (54) disposed in the pressure storage chamber (58) and biasing the pressure storage plunger (53) toward the close position, the trigger-type ejector being configured such that, when a pressure of a liquid in the pressure storage chamber (58) becomes equal to or greater than a predetermined value, the pressure storage plunger (53) moves from the close position to the open position against a biasing force of the biasing member (54) and thus a liquid in the pressure storage chamber (58) is ejected from the ejection hole (51c) to the outside.
